Need help with Ti-89 calc.
Somehow i got stuck in sometype of program inside the calculator and I seem to can't quit the program or something.
Like when i type 2+2 it gives me 0h4.If type 100 + 2, it switchs 100 to 100. and gives me the answer as 102.
I just want it go back to the way i had with it.When i put 2+2 in there it will give me 4.
